  This function decodes the image which the image type of this image is supported\r

  to put the image in the given image buffer. That allows the caller to put an\r
  image overlap on the original image. The transparency is handled by the image\r
  decoder because the transparency capability depends on the image format. Callers\r
  can set Transparent to FALSE to force disabling the transparency process on the\r
  image. Forcing Transparent to FALSE may also improve the performance of the image\r
  decoding because the image decoder can skip the transparency processing.  If **Bitmap\r
  is NULL, the image decoder allocates the memory buffer for the EFI_IMAGE_OUTPUT\r
  and decodes the image to the image buffer. It is the caller?s responsibility to\r
  free the memory for EFI_IMAGE_OUTPUT. Image decoder doesn?t have to handle the\r
  transparency in this case because there is no background image given by the caller.\r
